To all whom may concern:

Be it known that 1, WILLIAM A. Tuna citizen of the United States, and a resident of Lancaster, county of Erie and State ot New York, have invented certain new and useful Improvements in Electrical Systems or Distribution, of which the following is a specification.

My invention relates to electrical systems or. distribution and apparatus therefor and is more especially designed for use in systems in which a storage battery\ is connected to supply consumption circuit at times when the main source of electrical energy 1 1S 1110 aerative.

terns l have specifically designed my improvements with relation to train lighting syswhich it is desired that the battery feed as lighting or consumption circuit when the main generator is not working, and in whica it is desirous to maintain the voltage or" the consumption or work circuit 'substantiad 1 a lever 12 y constant although the potential of the battery may vary greatly between charge discharge.

(l ne 0..

grammatically represents a system embodying one form of my improvements.

in the drawing 1 represents a main generator feeding the work or consumption circuit 2, 2 of lamps or other translating devices. iicross the terminals of the generator is connected a storage battery 3. Between the generatorl and the consumption circuit 2 and in series therewith is a carbon pile resistance 4-. This carbon pile resistance may be varied by pressure thereupon, exerted by a lever 5 under the action of a spring 6. lhe spring 6 may be adjusted by screw 'Z and nuts 8. Connected across the consumption circuit 2, i2, is a solenoid 9 and in series therewith is a second carbon pile resistance 10. The solenoid 9 is arranged to act upon. and operate a core 11, which in turnoperates The lever 12 is mechanically 3 ct of my invention is toprovide arrangement and apparatus whereby the connected with the lever 5 by a link 13, and the link 13 is loosely connected with a lever 12 by means of a slot 14 and pin 15. This arrangement is such. that the leverrllZ may have some movement during a certain part of its operation without causing any movement of the lever 5. A dash pot 16 is arranged at thelower end of the core 11 to prevent injurious results due to jarring, etc. The carbon pile resistance 10 is operated by means of a bell crank lever 17 which com presses the pile 10 under the action of a spring 18 connected to the lever 12 as shown. The tension of the spring vl8 may be adjust ed by means of screw 19 and nuts 20..

In operation when the generator 1 is idle or is not producing sufiicient voltage for the work: circuit the battery 3 feeds the work circuit at substantially its normal discharge voltage. l'rlowever when the generator is feeding the system, in order to cause the battery to charge, it is necessary that the generator voltage be greater than the discharge voltage of the-battery. In order to prevent this excess voltage from fallin upon the translating devices of the wor circuit the variable resistance t is so operated that the potential drop therethrou h is greatly increased in order to bring t e voltage applied to the work circuit to its normal value. This is done by the action of the solenoid 9 which the potential across the work circuit 2, 9: increams thereby has its strength increased so that the lever 12 is raised, causing long arm of the lever 5 to be raised against the action of spring 6, thereby decreasing the pressure of the blocks of the carbon pile 4 so that its resistance is greatly increased. This increase oi resistance of the. carbon pile 42 causes a greater drop of therethrough and tends to bring the voltage applied to the work circuit back to its normal value. order to increase or magnify this action the carbon pile resistance 10 is operated in the circuit-in series with solenoid 9. As the lever 12 is raised under the action of the solenoid, 9, the tension exerted by the spring 18 upon lever 17 is increased thereby increasing the pressure upon the carbon pile 10 to decrease the resistance of the solenoid circuit thereby increasing the strength of the current therethrough and increasing or magnifying its action upon the carbon pile resistance 4.
